Complex three-dimensional multi-layer structure and manufacturing method thereof

Abstract

The present invention relates to a 3-dimensional complex multilayer structure. The 3-dimensional complex multilayer structure includes a first pattern and a second pattern having different thicknesses formed on one or both surfaces of a plate. The first pattern is selected from the group consisting of parallel lines, parallel curves, parallel zigzag lines, and combinations thereof which do not meet each other. The second pattern is not parallel to the first pattern and is selected from the group consisting of parallel lines, parallel curves, parallel zigzag lines, and combinations thereof which do not meet each other. The interfaces between the first pattern and the second pattern form figures selected from the group consisting of polygons, circles, ellipses, and combinations thereof. The figures are repetitively formed on one or both surfaces of the plate. The 3-dimensional complex multilayer structure includes different complex patterns, whereas a conventional device has a kind of simple pattern. The 3-dimensional complex multilayer structure of the present invention can be manufactured by a simple process. Therefore, the 3-dimensional complex multilayer structure of the present invention can find application in various fields, including optical components for displays (e.g., light guide plates, diffusion plates, prisms, and color filters), next generation displays and display devices (e.g., TFTs, OTFTs, oxide TFTs, flexible displays, and transparent displays), next generation 3-dimensional semiconductors, dry adhesion based on the use of fine ciliary structures, micro / nano piezoelectric devices, lighting optical components, and biocell / virus research using micropatterns.

Benefits of technology

The present invention relates to a 3-dimensional complex multilayer structure that includes different complex patterns and can be manufactured by a simple process. This structure can be applied to various fields such as optical components for displays, next generation displays and devices, next generation 3-dimensional semiconductors, lighting optical components, and biocell / virus research using micropatterns. Particularly, the structure can achieve improved economic efficiency and reduced thickness compared to conventional components, and can be combined with a diffusion sheet to realize a front luminance above the level of a conventional component and reduce optical loss caused when light passes through multiple optical sheets. The production process of the optical component is simplified, and the stability and economic efficiency of the process are improved. The method of the present invention simplifies the production of a multilayer fine ciliary structure and can be repeated multiple times, enabling the formation of a pattern consisting of four or more layers. It can also utilize an existing system based on an imprinting process, thus being suitable for mass production.

Problems solved by technology

Thus, backlight assemblies as separate devices for irradiating light onto liquid display panels are inevitably required in liquid crystal displays.

The light guide plate or the diffusion plate suffers from the disadvantage of very low exit angle or front luminance, which increases the number of the optical sheets stacked thereon.

As described above, optical sheets used in displays are large in number and are expensive.

Thus, a reduction in the number of optical sheets used in displays is considered a major technical issue.

However, multifunctional optical sheets developed based on the conventional techniques fail to meet requirements in terms of image quality such as luminance and contrast, which can be achieved by conventional optical sheets.

However, these methods require two or more processes to form a multilayer pattern consisting of two or more layers and greatly limit the structure or size of a second or third pattern to be formed.
